As of 2026-08-21, the tracked universe spans 2,066 companies across eight sectors. Two very different rankings emerge depending on whether you count names or weigh capital — and the divergence is the most interesting thing in the data.
Breadth: Technology runs the board
By company count, Technology is unrivaled with 574 names, roughly 28% of the entire universe. Its sample reads like the sector's spine: Apple, Microsoft, NVIDIA, AMD, Salesforce, and Intel. Behind it come Industrials (400) and Healthcare (342), giving the top three sectors a combined footprint of over 63% of tracked tickers.
The long tail is populated and global. Industrials mixes Honeywell and nVent with Xiamen Solex, Taiwan's Arch Meter, and speculative names like Archer Aviation. Basic Materials (273) leans heavily international — Chinese fertilizer, Argentine lithium, and cross-listed miners such as Novo Resources and Galantas Gold appearing under multiple exchange suffixes. This is a wide, multi-market universe, not a US-only screen.
Weight: Financials and Energy dominate the cap table
Rank the same sectors by reported aggregate market cap and the order inverts. Financials leads at roughly $159T (reported, in millions), fronted by Berkshire, JPMorgan, Visa, Mastercard, and Bank of America. Energy follows near $107T — Exxon, Shell, and Reliance — despite carrying only 123 names. Basic Materials sits third around $47T.
Technology, for all its breadth, ranks only fourth by reported weight (~$23T). The clearest mismatch is Industrials: 400 companies but a comparatively modest ~$12T, and Consumer Cyclical, which despite housing Amazon and Tesla shows the smallest aggregate figure in the set.
What to watch
The breadth-versus-weight split is a structural signal for anyone screening this universe. A naive equal-weight scan will be pulled toward Technology, Industrials, and Materials simply because that is where the tickers are. A cap-weighted lens tells the opposite story, concentrating exposure in Financials and Energy.
A few practical watch-items:
- Concentration risk in Financials and Energy. A handful of mega-caps in these two sectors carry the majority of reported weight — moves there dominate any cap-weighted view.
- Data hygiene on cross-listings. Names like Tesla (TL0.F, TL0.DE), Alphabet (GOOGL, GOOG), Novo Resources, and Obsidian Energy appear under multiple tickers. Any breadth count should be read as listings, not strictly distinct companies.
- The reported-cap figures themselves. The aggregate weights are large and should be treated as directional rankings rather than precise valuations until reconciled against a clean source.
The takeaway: this is a broad, tech-heavy universe by count but a financials-and-energy universe by weight. Knowing which lens you are using is the difference between diversification and unintended concentration.
